Voc\u00ea pode usar a seguinte sintaxe b\u00e1sica para exibir porcentagens no eixo y de um histograma no ggplot2:<\/span><\/p>\n

 library<\/span> (ggplot2)\nlibrary<\/span> (scales)\n\n#create histogram with percentages\n<\/span>ggplot(data, aes<\/span> (x = factor<\/span> (team))) +  \n  geom_bar( aes<\/span> (y = (..count..)\/ sum<\/span> (..count..))) +\n  scale_y_continuous(labels=percent)\n<\/strong><\/pre>\n
 Os exemplos a seguir mostram como usar essa sintaxe na pr\u00e1tica.<\/span><\/p>\n
 Exemplo 1: histograma b\u00e1sico com porcentagens<\/strong><\/span><\/h3>\n
 O c\u00f3digo a seguir mostra como criar um histograma para vari\u00e1veis categ\u00f3ricas com porcentagens exibidas no eixo Y:<\/span> <\/p>\n
 library<\/span> (ggplot2)\nlibrary<\/span> (scales)\n\n#define data frame\n<\/span>data <- data. frame<\/span> (team = c('A', 'A', 'A', 'A', 'B', 'B', 'B', 'C', 'C', 'C', 'C') ,\n                   points = c(77, 79, 93, 85, 89, 99, 90, 80, 68, 91, 92))\n\n#create histogram with percentages\n<\/span>ggplot(data, aes<\/span> (x = factor<\/span> (team))) +  \n  geom_bar( aes<\/span> (y = (..count..)\/ sum<\/span> (..count..))) +\n  scale_y_continuous(labels=percent)<\/strong> <\/pre>\n
\"\"<\/p>\n
 Exemplo 2: histograma com porcentagens (remover decimais)<\/strong><\/span><\/h3>\n
 Voc\u00ea tamb\u00e9m pode usar o argumento de precis\u00e3o<\/strong> para exibir apenas n\u00fameros inteiros como porcentagens no eixo y:<\/span> <\/p>\n
 library<\/span> (ggplot2)\nlibrary<\/span> (scales)\n\n#define data frame\n<\/span>data <- data. frame<\/span> (team = c('A', 'A', 'A', 'A', 'B', 'B', 'B', 'C', 'C', 'C', 'C') ,\n                   points = c(77, 79, 93, 85, 89, 99, 90, 80, 68, 91, 92))\n\n#create histogram with percentages\n<\/span>ggplot(data, aes<\/span> (x = factor<\/span> (team))) +  \n  geom_bar( aes<\/span> (y = (..count..)\/ sum<\/span> (..count..))) +\n  scale_y_continuous(labels = scales ::<\/span> percent_format(accuracy = 1L<\/span> ))<\/strong> <\/pre>\n
\"Histograma<\/p>\n
 Exemplo 3: histograma personalizado com porcentagens<\/strong><\/span><\/h3>\n
 O c\u00f3digo a seguir mostra como criar um histograma com porcentagens exibidas no eixo Y e um t\u00edtulo personalizado, r\u00f3tulos de eixo e cores:<\/span> <\/p>\n
 library<\/span> (ggplot2)\nlibrary<\/span> (scales)\n\n#define data frame\n<\/span>data <- data. frame<\/span> (team = c('A', 'A', 'A', 'A', 'B', 'B', 'B', 'C', 'C', 'C', 'C') ,\n                   points = c(77, 79, 93, 85, 89, 99, 90, 80, 68, 91, 92))\n\n#create histogram with percentages and custom aesthetics\n<\/span>ggplot(data, aes<\/span> (x = factor<\/span> (team))) +  \n  geom_bar( aes<\/span> (y = (..count..)\/ sum<\/span> (..count..)), fill = ' lightblue<\/span> ') +\n  scale_y_continuous(labels=percent) +\n  labs(title = ' Breakdown by Team<\/span> ', x = ' Team<\/span> ', y = ' Percent of Total<\/span> ') +\n  theme_minimal()\n<\/strong><\/pre>\n
